SKATE-SETAPUPENING STAND.

Application filed June 28, 1920.

To aZZ zo/02nz't may concern:

Be it known that I, CHARLES A. Rrrrnn, a citizen of the United States,residing at Chicago, in the county ot Cook and State of Illinois, haveinvented new and useful Tmprovements in Skate-Sharpening Stands, of'which the following is a specification.

This invention relates to a device tor holding a pair of ice skateswhile being sharpened, and consists in the matters hereinafter describedand more particularly pointed out in the appended claims.

In the accompanying drawings- Figure 1 is a side view of a skate holderconstructed in accordance with my invention and shown clamped to a tableor bench edge and holding a pair of skates in position Jfor sharpening;

Fig. 2 is an enlarged vertical sectional view taken on line 2 2 of Fig.1; and

Fig. 3 is a top plan view ot the parts shown in Fig. 2.

The device of my invention comprises two plates 1 and 2, arranged oneabove the other and each being made ot sheet metal to be light in weightand inexpensive and easy to manufacture. The lower plate 1 isrectangular and fiat and has side flanges 3, 3 curved upward and inwardtoward each other to conform to the curvature of the runner housingtubes 4, 4f of the skates te be held in the holder and to tit about saidtubes on the outside thereof, as shown in Figs. 2 and 3. The top plate 2is also rectangular and tits between the side flanges 3, 3. rThe plate 2has side flanges 5, 5 extending upward and curved outward to conform tothe curvature of the tubes 4, l and to nt against the same opposite thelianges 3, 3 to clamp the tubes between them with the runners G, 6carried by said tubes projecting above the lianges, as shown. Thellanges on said plates may be formed b v bending the side portions otthe plate to Jform them, as shown, and being parallel hold the skates inthat position and also relatively close together. To clamp the tubes tbetween said {ianges 3, 5, a screw bolt 7 is secured to the under plate1 and extends upward therefrom through a hole in the top plate 2 andthere receives a clamp nut 8, which may be ot the winged or butteriiytype to permit it to be more readily grasped and turned. The screw bolt7 is arranged within the center ot the plates 1,

2, as shown in Fig. 3, and the upper plate 2 is curved transverselyupward from its side iianges to give it resiliency and permit it to beflattened out in clamping the skates in the holder, when the nut istightened for that purpose. Thus only one screw bolt and only two platesare required, therefore making the device have but a few parts and thosesimple to manufacture and apply.

To support the holder above an underlymg support, such as a table orbench 9 (Fig. 1), a distance suilicient to holdl a pair ot skates withshoes attached above the table, I employ a bracket, which as shown inthe drawings has an upright supporting post 10, made hollow to receiveat its upper end a stem 11 secured to the under side of the plate 1, atthe center. This stem 11 is adjustably held in the post by a set screw12 to vary the height of the holder above the table to clear the shoesoil the table, when the occasion demands. At the bottom orF the postaretwo jaws 13, 13, rigid therewith to receive between them the edge ot thetable 9 and be clamped thereto by a clamp screw 14 threaded through thelower jaw.

In use, the device `described and shown is applied to the edge of atable or bench 9 and the top plate 2 removed. The pair of skates to besharpened are placed inverted on the bottom plate 1 with the platebetween the front and rear cups of the skates, as shown in Fig. 1, tobalance them in the holder. The top plate 2 s then applied and clampedin place between the skates and the latter are held with their runners 6projecting upward with their running edges in the same horizontal planeand close enough together to have an oil or other sharpening stone 15(dotted lines,4 Fig. 1) extend between and rest on such edges forsharpening the same in the movement of the stone thereover. The bottomplate 1 being flat, the runners G, 6 project above the plate the samedistance and thus bothy runners may be sharpened evenly and to the sameextent by one stone at the same time.

I claim as my invention:

1. A device for holding a pair ot ice skates while being sharpened,comprising a top plate and a bottom plate having parts to receivebetween them and hold a pair of skates relatively close together withtheir runners extending above said plates and substantially parallel,and fastening means to Jforce one of said plates toward the other forclamping the skates between said parts.

2. A device for holding a pair of ice skates while being sharpened,comprising a curved top plate and a flat bottom plate having sideflanges to receive between them and hold a pair of skates relativelyclose together` with their runners extending above said plates andsubstantially parallel, a single screwthreaded bolt secured to one plateat the center and extendingA through a hole in the center of the otherplate, and a nut applied on the threaded end of said bolt to force oneplate toward the other for clamping` the skates therebetween.

3. A device for holding a pair of tubular ice skates while beingsharpened, comprising a Curved top plate and a flat bottom plate havingthe side portions thereorl bent to provide flanges extending toward eachother and curved to engage and lit about the runner housing tubes ofsaid skates, and Jfastening means to force one of said plates toward theother for clamping the skates between said flanges.

4. A device for holding a pair of tubular iceV skatesV while beingsharpened, comprising a curved top plate and a flat bottom plate havingthe side portions thereof bent to provide flanges extending toward eachother and curved to engage and lit about the runner housing tubes ofsaid skates, a screwthreaded bolt secured to the bottom plate at thecenter and extending through a hole in the center of the top plate, aclamp nut applied against said top plate on the threaded end of saidbelt, and a bracket secured to the under side of said bottom plate andadapted to engagean underlying support for sup`vporting said platesabove the same.

In testimony that I claim the foregoing as my invention, I affix mysignature, this th day of June7 A. D. 1920.

CHARLES A. RITTER.
